John Davidson is a university lecturer, who, at the age of 28, has already begun to see signs of ageing on his face. He has experimented with various lotions but, profoundly frightened about growing older, he takes a more drastic step - he takes Pro Clear, a new anti-ageing drug which keeps his physical age at a constant 28. The Man who didn't Age tracks John's development through the ensuing years. How does he take advantage of the fact that he's not ageing? How does he continue to relate to his friends? This fast-moving novel tackles a number of existential questions and finishes in an unexpectedly poignant way.
